SQL::Schema::Procedure
is a class for objects representing a procedure
stored within the database.
The methods of an instanciated object do allow to access the
information within a database's data dictionary and to represent them as SQL
create statements and the like using the proper SQL dialect.
$procedure = SQL::Schema::Procedure->new(%attr);
The new method instanciates a procedure object. The object is
an in memory representation of a (possible) database procedure.
The attributes are given as key value pairs by the hash %attr
.
Possible keys are:
key required? value description
name yes the name of the procedure without preceeding schema name
text yes the concatenation of all the text lines forming the procedure's source code
As a procedure is basically a piece of source stored within the
database, this class inherits all methods from SQL::Schema::Source
.
So please have a look at the new method describet at
the SQL::Schema::Source(3) manpage. Though the new method here overwrites
the new method there, it calls the super class's new method
with just the key value pair for the source's type
added.
$procedure = SQL::Schema::Procedure->select($dbh,$name);
The select method fetches the attributes required by new from the database and returns the procedure object. (It calls new internally.)
If the procedure with the name $name
could not be found within
the database, the method returns undef.
The method's arguments are as follows:
$dbh
$name
The following attribute methods do exist:
$type = $procedure->type;
The method type
always returns the string ``procedure
''.
This package inherits all the other methods from SQL::Schema::Source
as a database procedure basically is a special kind of source within
the database. For more information, please have a look at
the SQL::Schema::Source(3) manpage.
